Patented Aug, 9, 1932 UNlTI-:o fSTATES PATENT! oFFlcE JONATHAN NEWTON.WHITE, OF NEW YORK. N. lY., ASSIGNOB TO UNITED METAL HOSE CO. INC., OFNEW YORK, N. Y., A. CORPORATION OF NEW YORK NOZZLE Application ledAugust 27, 1928. Serial No. 302,155.

This invention relates to nozzles and metal lined hose -of the type usedto dispense inflammable liquids, and most' particularly gasoline fromfuel stations and filling devices to automobile tanks.

An object of this invention lies in the provision of a simple strongstructure which will positively engage the hose'end and form a nozzletherefor without intermediary fittin s or parts and will when engagedwithI Suc hose form, for all practical purposes, a unitary part thereofand remove any likelihood of accidental detachment in service so thatthis nozzle may lserve as a.- hanger forl character;-various makeshifts,grounding chains, wire clips and the like, have been tried but havefailed in that seldom if ever were all of the metal parts always indirect electrical contact so that no potential difference couldexist'therebetween. It is the purpose of the herein disclosed inventionto automatically provide direct contact between, and grounding of, themetallic hose and nozzle and the tank or other container into whichdischarge is made without other media than the parts themselves andwithout other operation than that involved by the usual use of the saidpartsfor Huid discharge. y

It is also a function of the herein disclosed invention to provide meansfor protecting* permitting use of rubber" and like materials where suchare best suited 4and for the complete isolation of such materials fromthe fluids handled.

Reference to the following description, the attached drawing, and theappended claims will serve to further disclose the above, and certainother improvements and objects accomplished by this invention.

Figure 1 is a side elevation of an embodiment of my invention, a portiononly of the hose being shown and the main part of the structure beingbroken away substantially on its center line to facilitate description.

Figure 2 shows a modification of the embodiment of Fig. 1 and is takenin substantially the same fashion as that ligure.

Figure 3- serves to illustrate a hose embodying my invention in actualuse.

A preferred formof metallic hose 9 utilized a for the purposes describedconsists of a Woven fabric outer cover 10, a rubber layer 12, and ametal lining 14. This hose, in one of its most common uses, Aextendsfrom the gasoline dispensing pump to-the automobile tank to be filledand into whose filling opening 16 the gasoline is to be discharged. Itwill be understood that the openings 16 in vdifferent automobiles arelocatedin various positions and vary in size and shape so thaty I anelongated discharge portion 21 of the hose nozzle 20 is customarily provided for convenience in inserting the nozzle in the tank opening andthat a holding lug 22 serves to assist in holding the nozzle in positionin the tank opening. The pump end of the hose 9 is preferably united tothe gasoline pump 11 in such fashion that metallic lining 14 forms acontinuous extension o'f the metal parts thereof (which are thoroughlygrounded through tank llt) and it is one of the important featuresv ofthis invention that the novel form of nozzle now disclosed permits afurther metallic extension of the said completel grounded parts and forthe completion'o an all metal conduit and connection 'to the tankopening 16 and the metal parts of the car, preventing contamination ofthe gasoline, destruction of the rubber and fabric portions of the hose,and anyelectrical potential dierence capable of/p'roducing a sparkbetween the parts. -f The nozzle 2o has a discharg ltending therethroughand surrunded at'the bore 23 ex-g n hose end by a recess 24 slightlylarger than the hose 9 whose end extends into this recess and abutsagainst a suitable shoulder or gasket 26 at the inner end of the recess.'llhe body of nozzle is enlarged to accomodate recess 24.- and upon thisenlarged portion ll prefer to provide a thread or equivalent engementdevice 28 and a convenient h olding ange 29 which may be six or eightsided to accomodate a wrench, if desired. 'lhread 28 serves for theengagement of sleeve which is internally threaded, as indicated, so thatit may be drawn and tightened upon the nozzle body, a wrench applicationportion 32, somewhat similar to dange 29, providing for ositiveengagement between the parts. leeve 30 is internally recessed at 34: toaccommodate a helical compression member 40 (see also Fig. 3) whichengages the outer surface of the hose 9 and which (when the sleeve 30 istightened on the body 20) is compressed thereon and lsecurely clamps thehose while at the same time permitting the movement of sleeve 30, as itdraws upon the body 20, to ltorce the end of hose 9 tightly againstshoulder or gasket 26 and to tightly seal the end of the hose to thenozzle body.

The positive seal between the metallic lining 14 of the hose 9 and thebody of nozzle 20 is further aided, while an electrical contact isautomaticall and securely edected, by a projectionlor ange upon body 20entering and engaging the metal lining lt and uniting it with the metalof body 20 so that the two are mechanically and electrically a singleunit when so joined. .This construction will be seen to completelyeliminate intermediary ttings and then unavoidable acked joints, thussubstantially reducing the iability to leakage or failure while reducingthe cost of construction and increasing the strength and usefulness ofthe structure as a whole. v

It will be understood that utilization of the means above set forth soapplies the nozzle to the hose that accidental separation therebetweenis almost an impossibility, compreion member 40 gripping the hose lmoreti htly as pull between the ytwo increases. T us itis entirely practicalto' place a hanger 52 upon the exterior of nozzle 20 and for such hangerto replaceany form of hanger former needed on the hose itself thuseffecting an a ded function and a substantial improvement over directhanger contact with the outer hose cover l() and its consequent earlydestruction. Hanger 52 is here shown as 1n th e form of a ange adaptedto be placed within the forks of a suitable holder ll-t secured'to thegasoline ump (see dotted lines Eig. 3 for the hose in ung up position)or like convenient support, but it will be understood that. a hook orlike hanger may be equally well incorporated in the nozzle struc- .turewhen desired.

nemica Figure 2 serves to illustrate that embodiment of my inventionwherein the rlgid elongated portion 21 of the nozzle is replaced by asuitable ilexible portion 21a which 1s also positively mechanically andelectrlcally joied with the nozzle body at and .whlch may extend to suchlength and direction as desired and thereby facilitating nozzleapplication in many instances.

The exible portion 21a will be seen to 1n no way prevent useful applyingof all of the means hereinbefore described and it will be noted that theuniting and protective functions are fully performed as in the precedingembodiment like numerals having been applied to like parts in thedrawing.

While l have described my device as particularlysuited `for thedispensing of gasoline and like inlammableiiuids it will be manifestthat many ot /r uses are possible and while certain en odiments havebeen set forth as preferabl it will be understood that many modicati nsin the whole and lin the parts thereof are well within the scope of myinvention and the spirit of the appended claims.
